Abstract
A remote monitoring system for instrumentation that is capable of measuring certain characteristics of a process such as a pH value includes an instrument for providing a measurement output signal which can be stored. A comparison circuit can compare the output signal with a predetermined value. A transmitter can transmit when the output signal exceeds the predetermined value, and a receiver can receive the output signal and convert it into a measured result. The instrumentation can be pulled from the receiver and the output signals can be encoded to identify a particular instrument with distinct transmission time periods available in a plurality of transmitting channels.
